You are looking at an Athearn Genesis HO scale model of an Alaska Railroad SD70MAC, number 4006. "Spirit of Anchorage" It has hardly been run at all, but it does run well. It's in great shape, as I have kept it in its original box when it's not on the layout. You're probably aware that this is a discontinued road number from Athearn, as are all of their Alaska SD70MACs. It will ship in its original box, with original packaging, and will include original documentation. I will also be listing other Alaska SD70MACs, so check them out too. Happy bidding!
